Im tryed to modifi the extension to work on internal img and url tags.
Aksly it works, buth i not exactli know what i'm dan. I think whidt this modification, the handle_center_tag definition is not required.
Is this secure?

<hook id="ps_do_bbcode_replace"><![CDATA[
                                          
                                          // add pattern to catch [center]blahblah[/center]
                                          $pattern[] = '#\[center\](.*?)\[/center\]#ms';
                                          $replace[] = '<div style="text-align:center">$1</div>';
                                          
                                          ]]></hook>
